How to refresh entire application when date is changed in angular 9 ?

In this example, we will see how to refresh the application when the date is changed in angularJS.

Approach:

• First, we need to write the code for displaying the date picker in an HTML file.
• We can achieve this by giving the input type as the date.
• After completing the input type, we need to declare a function on the ‘onchange’ event so that whenever the date is changed or modified the application will be reloaded.
• After declaring the function in the HTML file we need to write the function implementation in the ts file.
• In the function implementation, we can use the window property of DOM, and we can call the reload function so that the application is reloaded.
• After completing the above steps, serve or start the project.

Code Implementation:

app.component.ts:

Javascript

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    constructor() { }

    // Function to reload the application
    refreshPage() {
        window.location.reload();
    }
}

app.component.html:

HTML

<h1>Hello User !</h1>

<p>Change the date to refresh the application.</p>

<input type="date" (change)="refreshPage()">

app.module.ts:

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

@NgModule({
    imports:
        [
            BrowserModule,
            FormsModule
        ],
    declarations:
        [
            AppComponent
        ],
    bootstrap:
        [
            AppComponent
        ]
})

export class AppModule { }

Output:
